MC nylon wheel closed type mold with integrated metal core

Abstract

The invention provides a MC nylon wheel closed type mold with an integrated metal core. The MC nylon wheel closed type mold with the integrated metal core comprises an upper mold, a lower mold, a central washer, the metal core and a pouring gate, wherein the upper mold is fixedly connected to the lower mold by the central washer; rubber seal rings are arranged between the central washer and the upper mold and between the central washer and the lower mold; the metal core is located by the lower mold; a gland is arranged at the upper end of the metal core; the pouring gate is arranged at the top of the upper mold and is connected to a S-shaped bending channel; a heating device is arranged on the peripheries of the upper mold and the lower mold; seal properties between the central washer and the upper mold and between the central washer and the lower mold are reinforced due to arrangement of the rubber seal rings; and the S-shaped bending channel enables the speed of a pouring material entering the mold to be effectively controlled, thereby reducing generated air bubbles and improving the quality of nylon wheels. The mold is simple to operate, wide in application range and suitable for pouring elevator rope wheels, crane pulleys and various wheel bodies.

Description

technical field [0001] The invention relates to the technical field of centrifugal casting molds, in particular to a one-piece metal core MC nylon wheel metal core sealed mold. Background technique [0002] The traditional metal core is pressed into the wheel hole, or fixed with glue, or fixed with keys and pins, or fixed with a retaining ring in the hole, which is not only costly, but also not as firm as casting, so the application of nylon wheel casting technology was born, but At present, the casting of nylon wheels in the market is easy to cause blisters in the casting process due to the simple casting mold, which affects the quality and appearance of nylon wheels. Contents of the invention [0003] In order to overcome the above defects, the present invention provides a one-piece metal core MC nylon wheel closed mold with good casting effect and guaranteed nylon wheel quality. [0004] The technical scheme adopted by the present invention to solve the technical probl...
